AutoZone posted disappointing earnings in May.
Shares are also falling due to weak international sales.
The stock now trades at a much more reasonable price than before.
Shares of AutoZone (NYSE: AZO) sank 21% in May, according to data from S&P Global Market Intelligence. Despite the broader market soaring, retailers such as AutoZone have struggled in recent quarters due to rising inflationary costs and unimpressive growth. AutoZone once again disappointed investors when releasing quarterly earnings in May, sending the stock lower.
Here's why AutoZone stock tumbled last month, and whether now is a good time for investors to buy the dip.

AutoZone released its earnings for the quarter ending May 9th in late May. Revenue grew 8.4% year over year to $4.84 billion, slightly missing Wall Street expectations.
More importantly, AutoZone's same-store sales growth slowed down in the quarter, at 4.1% domestically and 1.6% internationally in constant currency. Same-store sales are an important metric for a retailer, as it measures revenue growth from existing units. If same-store sales growth comes in below inflationary inputs, that can put pressure on profit margins.
AutoZone is generating solid same-store sales growth domestically, but it is internationally where investors are likely pessimistic. The company is embarking on a large expansion across Mexico and Brazil, risking its brand in new countries. It has 157 stores in Brazil and 933 stores in Mexico. If same-store sales growth continues to lag in these markets, it may signal that the AutoZone brand is not performing as well as it does in the United States.
From a profit standpoint, AutoZone delivered steady growth yet again. Net income was $641 million, up 5.4% from a year prior, but growing more slowly than revenue. Management continues to utilize its share repurchase program, spending $586 million on buybacks last quarter alone. Shares outstanding are now down around 90% from their peak at the turn of the century.
With the stock falling, these share repurchases will be much more impactful on reducing the share count. Right now, AutoZone trades at a price-to-earnings ratio (P/E) of 21, down from a peak of 30 in 2025. This is a much more palatable P/E ratio for a slow-growth business like AutoZone, especially given its stock repurchase program.
For those who believe in AutoZone's steady expansion in the United States and Latin America, the stock could be much more attractive to buy after its May decline.

Four leading AI models discuss this article
"Near-term upside depends on a LATAM turnaround and margin expansion; without clearer progress there is meaningful downside risk to AZO stock even after the May drop."
The May decline in AZO looks anchored by a slower growth trajectory, notably international SSS of 1.6% vs 4.1% domestically, and a P/E compressing to 21x from ~30x. Revenue grew 8.4% to $4.84B, net income +5.4%, yet margins and earnings growth aren’t keeping pace with the multiple’s prior peak. The LATAM push (933 Mexico, 157 Brazil stores) carries execution, currency and macro risks that the article glosses over. Buybacks ($586M) aid EPS but only if cash flow stays robust. Missing context includes gross/operating margins, capex cadence, debt/currency sensitivity, and LATAM profitability cadence—key drivers of whether the multiple re-rating is justified.
The international expansion could be a long-duration hurdle with volatile currencies and weaker near-term SSS; the stock’s decline may reflect growing structural risks rather than a one-off multiple reset.
"AutoZone’s aggressive share buyback program provides a reliable floor for EPS growth that compensates for the slowing revenue expansion in emerging markets."
AutoZone’s 21% drawdown is a classic valuation reset, not a structural collapse. While the article fixates on slowing international same-store sales, it glosses over the company's aggressive capital allocation strategy. Reducing the share count by 90% since 2000 is a massive tailwind for EPS (Earnings Per Share) growth, even in a low-growth revenue environment. At a 21x P/E, AZO is finally trading at a level that accounts for its mature lifecycle. Investors are paying for a defensive 'compounder' that benefits from the aging U.S. vehicle fleet, which currently averages over 12 years. The international expansion is a secondary growth lever; the core domestic business remains the primary cash-flow engine.
If domestic DIY demand cools further due to high interest rates discouraging new car purchases—which usually drives repair demand—the stock lacks a growth catalyst to justify even a 21x multiple.
"AZO's margin compression and international SSS collapse signal structural demand weakness, not a cyclical dip—buybacks are masking deterioration, not creating value."
The article frames AZO's 21% drop as a buying opportunity, but misses critical structural headwinds. Yes, the P/E compressed from 30 to 21—attractive on paper. But revenue growth of 8.4% with net income growing only 5.4% signals margin compression, not temporary weakness. Same-store sales of 1.6% internationally is alarming: that's below inflation in most markets, meaning real volume is contracting. The $586M in buybacks last quarter masks deteriorating fundamentals—management is using financial engineering to prop up per-share metrics while the core business slows. Latin America expansion (1,090 stores combined) is unproven and capital-intensive; early weakness there suggests execution risk, not brand strength.
If domestic SSS of 4.1% reflects genuine pricing power and the international drag is temporary (new market ramp-up), then a 21 P/E on a 5%+ net income grower with fortress cash flow and a 40-year buyback track record could be genuinely cheap relative to quality.
"International same-store sales of only 1.6% during rapid Mexico/Brazil expansion signal execution risk that the lower 21x P/E does not yet price in."
AutoZone's 1.6% constant-currency same-store sales growth internationally, paired with aggressive store additions in Mexico and Brazil, points to potential brand or competitive weakness that domestic 4.1% growth cannot offset. Net income rose only 5.4% while revenue grew 8.4%, and the article underplays how sustained low-single-digit international comps could pressure margins more than buybacks can repair. The drop to a 21x P/E from 30x looks attractive only if expansion execution improves quickly; otherwise the multiple compression may continue. International risk is the clearest unaddressed overhang in the May sell-off.
Domestic same-store sales of 4.1% remain above inflation and the $586 million quarterly buyback will be more accretive at the lower price, potentially supporting EPS even if international growth stays muted.
"Margin compression and LATAM capex risk threaten profitability; buybacks alone won't justify a 21x multiple."
Claude overstates the durability of the buyback as a moat. My concern is margin compression from LATAM expansion and FX, not just a pause in growth. If international SSS stays around 1.6% and LATAM capex/work capital stays high, EBITDA margins may drift lower and free cash flow could weaken, limiting buyback-driven EPS upside. A 21x P/E looks risky if the re-rating hinges on aggressive capital allocation rather than improving core profitability.
"The aging vehicle fleet thesis is flawed because vehicle complexity is driving a structural shift away from DIY repair toward professional service."
Gemini’s reliance on the 'aging vehicle fleet' narrative is a dangerous simplification. While the average age of U.S. vehicles is at record highs, this doesn't guarantee DIY demand if consumers pivot to professional repair shops to avoid the complexity of modern, tech-heavy vehicles. If DIY growth flattens, AZO’s reliance on international expansion becomes a primary risk rather than a secondary lever. We are ignoring the shift in vehicle architecture that could permanently impair the DIY-centric business model.
"Domestic SSS of 4.1% is likely price-driven, not volume-driven, and masking the real margin compression risk that international expansion will amplify."
Gemini's vehicle-fleet thesis assumes DIY demand is inelastic to complexity, but the data contradicts this. If modern vehicles genuinely deter DIY repairs, domestic SSS wouldn't be 4.1%—it'd be decelerating. The real risk is that 4.1% domestic growth masks pricing power masking volume weakness. That's the margin compression story. LATAM's 1.6% SSS with new-store drag is expected; domestic deceleration would be the structural red flag nobody's watching.
"Vehicle complexity plus international weakness together create persistent volume and margin pressure that buybacks cannot fully offset."
Claude notes domestic 4.1% SSS might mask volume weakness, linking directly to Gemini's vehicle complexity risk. If rising tech in cars pushes more owners toward professional shops, even current domestic growth turns unsustainable and compounds the 1.6% international drag. This dual volume pressure makes the margin compression ChatGPT flagged more structural than temporary, implying the 21x multiple still prices in too much optimism on core cash flow durability.
Despite differing views on the cause, all participants agreed that AutoZone's recent performance and outlook warrant caution. The panelists expressed concern about slowing international sales, margin compression, and the sustainability of the company's capital allocation strategy.
